Hi,
I have been tasked with a kitchen rewire. The current DB is fed by a 16mm armoured.
There is a split load old contactum DB which I don’t fancy buying MCBs for.
I have quoted to add a sub DB with RCBO to cover my new kitchen wiring. My question is how would you feed the new DB?
Usually I would Henley block into the tails but as it’s being fed by an armoured where do I go? I see I have three options;
Feed the sub board via a 63a MCB though this allows for no discrimination via 16mm twin and Earth.
Complete DB upgrade to allow for new circuits
Or 16mm twin and Earth into the top of the main switch.
Advice please, note getting to the main incoming supply is not an option as too far across the house!
